You guuuuuuyssss. Ice is back at Verizon Center! On Wednesday afternoon, arena employees laid down the rink at Verizon Center, shaving the ice and dropping in lines and logos. I guess this whole hockey thing is really happening after all.

While we dedicate a lot of our time to RMNB, our team slaves away at full-time jobs just like you. Peter is an information architect, I’m a web designer/email marketer, and Fedor is a full-time student in Moscow and a journalist for VOA. Then there’s Igor.

Four score and seven years ago… okay, maybe not that long – but long enough that Scott Stevens was still a Capital and the Soviet Union was still a thing, Igor– fresh out of college– left St. Petersburg and the crumbling empire for America. Within a couple of months after getting off the proverbial boat, Igor landed his first job: an engineering position at the NASA Goddard Space Flight Center.

And two Fridays ago, one of Igor’s projects got global attention for a finding many thought was impossible decades ago.

Despite being our solar system’s innermost planet, Mercury’s poles are cold (like your feelings towards Sidney Crosby) because they never tilt towards the sun. Mercury’s thin atmosphere also can’t contain or insulate heat. Evidence for deposits of ice at both poles has been building since the early 1990s, when radar studies first spotted areas that looked very bright at radar wavelengths. These bright regions suggested something reflective lay on top of or very near the surface of the planet’s poles. Could it really be ice or maybe a box of Alex Ovechkin’s old face-shields? NASA set out to answer the question.

“Twenty years ago, radar astronomers made the startling proposal that there is abundant water ice at the poles of our solar system’s innermost planet,” Sean Solomon, the principal investigator for MESSENGER (short for MErcury Surface, Space ENvironment, GEochemistry, and Ranging), told NASA. “But alternative explanations of the radar observations have since been suggested, and the MESSENGER team set a high priority on settling this question with orbital observations.”

In 2002, the Mercury MESSENGER mission began. Before the orbiter was launched, a handful of scientific instruments needed to be created and built into the satellite: a fancy camera, a couple of spectrometers, a magnetometer, a radar, and a laser altimeter. The altimeter (MLA stands for Mercury Laser Altimeter) is the instrument that Goddard was asked to build. Igor and one of his colleagues of 20 years were given the assignment.

“A laser altimeter is a relatively simple instrument,” Igor, apparently not bragging, explained to me. “Its core is basically a laser and a time-interval measurement unit, which is a fancy term for a stopwatch. The laser fires a very short pulse of light at the surface of a planet, and when it goes out the clock starts running. The light travels for a period of time, reaches the surface, bounces off of it, and eventually gets back to the spacecraft – and that’s when we stop the stopwatch.”

Igor continued: “Take that time, multiply by the speed of light, divide by 2 since it’s a round trip – and voila! You have the distance from the spacecraft to the surface of the planet. And if your stopwatch is accurate to a fraction of a nanosecond (or one billionth of a second for those who are scared of fancy Greek words), you just measured that distance down to a couple of inches. Lather, rinse, and repeat a few hundred million times as the spacecraft is flying in a polar orbit – and you’ve got a nice topographic map of the planet.”

In addition, what NASA would be looking for once MESSENGER reached Mercury were nice, sharp, and strong pulses back. That meant they hit something very reflective, like a mirror, or in the case of Mercury, where it is very unlikely there are any mirrors, an ice patch!

So Igor and his colleague designed, built, tested, and delivered that fancy stopwatch (officially known as the Range Measurement Unit) to Messenger 10 years ago (seen below). On August 3, 2004, the 1,070 pound spacecraft was launched from Cape Canaveral, Florida, aboard a Delta II rocket. The spacecraft flew by Earth once and Venus twice before reaching Mercury in January of 2008. After three fly-by’s, taking three years to accomplish, MESSENGER successfully entered Mercury’s orbit on March 18, 2011. It sent its first photo back to earth 11 days later.

After a year of MESSENGER collecting and transmitting photos, maps, and data of Mercury back to Earth, NASA discovered ice on the planet’s north pole on November 30th. Igor’s fancy space stopwatch, which he described as one of the hardest things he’s ever built at NASA, was a success.

This might explain why that day, when I noticed a Russian language interview of Nicklas Backstrom ripe to be translated, Igor unexpectedly declined. “I just had a few beers in my meetings. I’ll explain later,” he said.

The Backstrom translation never happened, because in the words of Alex Ovechkin,”hahahaha ice.” Congratulations, Igor.
